Thank you all for your feedback. It is nice to have such a wealth of information and support here.
Everyone has been extremely helpful and I can't thank you enough.
Richard, The DPS Crime Lab sounds like a workable visit but I will have to schedule something around summer classes. I think I get a week off before fall classes begin.
Angel, I am glad to hear the MechEng & Physics are getting the same love that Chemistry & Biology get.
Bob & Bill, Thank you for the requirements. I am looking into ASCLAD lab requirements now.
As for the no felony, criminal background, pee in this cup tests, they are no problem. I had background checks for my concealed handgun license, my CDL license, etc. Besides, the Army is going to do a background check for any MOS that requires a security clearance.
Thanks again for everyone's help.
